摘要:耦合效率的高低与耦合后光斑的好坏直接影响着光子晶体光纤棒的放大效果，因此需要对种子光的耦合效果进行研究，选择合适的 器作为种子源。本文对光子晶体光纤棒在固体 器与光纤 器两种情况下的耦合效率进行了理论分析；模拟计算了两种 器情况下耦合效率的变化规律以及对准误差对耦合效率的影响；选择合适的透镜或透镜组，使用两种 器对光子晶体光纤棒进行了耦合实验；对比两种 器的耦合效果可知：固体 器的耦合效率最高只能达到62.4%，而光纤 器的耦合效率可以达到80%以上；在光纤 器耦合情况下，对不同功率注入时耦合效率，以及耦合后光斑进行了实验分析。得到的实验结果对后续光纤棒的放大实验具有指导作用。Abstract:The high or low coupling efficiency and the good or bad coupling facula directly affect the amplification effect of the Rod-type photonic crystal fiber. Therefore, it is necessary to research the coupling effect of seed light and choose a suitable laser as a seed source. In this paper, the coupling efficiency of Rod-type photonic crystal fibers in a solid-state laser and a fiber laser was theoretically analyzed. The changing regulation of the coupling efficiency and the effect of the alignment error on the coupling efficiency were calculated with two different lasers. A suitable lens or group of lenses were selected and an experiment was conducted to couple the solid-state laser beam and the fiber laser beam to the Rod-type photonic crystal fiber. Compared with the coupling effect of the two kinds of lasers, the maximum coupling efficiency of the solid laser is only 62.4%, while the coupling efficiency of the fiber laser is more than 80%. In the case of fiber laser coupling, the coupling efficiency at different power injection and the coupling facula were analyzed. The experimental results will guide the amplification experiment of the Rod-type photonic crystal fiber.
